- AUTOMATIC LUBRICATOR.

Specification of Letters Patent.

Patented Apr. 11, 1916.

Application filed'August 17, 1914. "Serial No. 857,075.

To all whom it may concern:

Be it kn" wn that I, DANIEL H. NICKELS, a citizen of the United States,and resident of Cleveland, in the county of Cuyahoga, andState of Ohio,have invented certain new and useful Improvements in AutomaticLubricators, of which I hereby declare the following to be a full,clear, and exact description, such aswill enable others skilled in theart to which it appertains to make and use the same. The-objects of theinvention are to provide an automatically acting device forrsupplyinglubrication to the journal box of an axle or shaft, and particularlyadapted to lubricate the journal box of a railway carv axle, so astoprevent overheating the axley when on the road.

Since long distances are traversed by rail- 7 way trains and it isimpossible to supply oil to them at sufliciently frequent intervals onroute, to prevent overheating a sufficient supply of lubricant must bestored in the journal box to last upon the trip or a large portionthereof, and be automatically ,applied to the axle and journal. Toaccomplish this object a journal box having a chamber capable of storinglubricant is provided and means are attached to the axle which by thecontinuous rotation there '1 of will automatically and continuously pourthe lubricant thereover.

The invention comprises the construction of box and self lubricatingaxle hereinafter described, shown in the accompanying drawings andspecifically pointed out in the claims.

In the accompanying drawings Figure 1 is a longitudinal section of a caraxle jour nal showing the storage reservoir and automatic lubricatingdevice; Fig. 2 is a transverse section looking into the box; Fig. 3 is aplan view of the spring which retains the wiper in position; Fig. 4 isan end view of one of the retaining nuts therefor; Figs.

.5 and 6 are side and plan views respectively of one of the retainingbolts therefor; Fig. 7 is a perspective view of the double cup bearingcross bars.

' In these views A is the journal box, hav-.

ing a hooded front portion A, in the lower portion of which thelubricant is stored. Transversely attached to the front end of the axleis shown a cross bar B which rotates freely in the hooded portion of thejournal box and in its projecting extremitoward the axle and take thelubricant which projects at C and into the trough shaped openings-d, d,inthe upper face of the bearing D, oil holes d, d lead from theseopenings to the axle. The front of the bearing D projects at D to soposition the openings cl .as toreceive freely the lubricant fromthecups,from which it is conveyed underneath the bearing-D andspread overtheaxle'h i The cups 1), b,'in each end of the transverse bar arepreferably two in number and are separated by means of a partition I),so as to act as'eiiiciently as possible in each direction as the axlerotates forward and backward. I i 'l A broad annular shoulder Euponwhichand pour it upon the front end of the, axle in and aninlet opening F isformed'therein.

at the lower end through which the cups receive the lubricant from. thebody of the journal box and the lubricant is delivered through anopening G at'the'central point above the axle. This shoulder'may be anattached band or ring if desired and of the same or difl'erentsubstancefrom thatof theI hood or journal box. j

The transverse bar B is preferably secured; to the outer end of the axleby means of one or more studs H, H, which are proa vided with squarestems inserted through square holes 6 6 in the bar -B which prevents thestuds from becoming loosened and a retaining spring B through which thebolts pass, rests at its ends upon the ends of the bar B andv maintainsthe bar in contact with the shoulder.

. The nuts J, J, are preferablyprovided with side flanges, j, j, whichare passed over the sides of the spring and prevent the, nuts frombecoming loosened. These precautions are necessaryon account of thecontinuous jar to which the axles are subjected.

A trough shaped and inclined member is seen at K which is some whatraised above 75 the cups revolve retainsthe lubricant there 1 Havingdescribed the invention What I claim as new and desire to secure byLetters Patent is: g

1. In a car axle lubricator, the combination with an axle provided witha pair of bearin ins 01 a lubricant transaortin bar provided withbearing openings mounted on and traveling upon said bearing pins,

a spring provided with openings loosely and movably mounted on saidbearing pins and having its ends impinging upon the outer ends of saidlubricant transporting bar, and spring retaining members adj ustablymounted on said bearing pins whereby the ends of said transporting-barmay be independently adjusted.

2. In a car axle lubricator, the combination with an axle provided atits ends with spaced bearing members, and a journal box provided with anaxle bearing above said axle and a lubricant reservoir below the latterand also having, lubricant ports communicating with said reservoir andsaid bearing; of alubricant transporting. bar loosely and resilientlymounted .on said spaced bearing members and having its ends providedwith lubricant carrying receptacles traversing said journal box andadapted to receive lubricant from said reservoir and discharge the sameto said bearingrmember through said lubricant ports, a bow springprovided with openings loosely and movably mounted on said spacedbearing members and having its ends impinging upon the outer ends ofsaid lubricant transporting bar and spring retaining members adjustablymounted on said spaced bearing members and normally interlocking withsaid bow spring for independently adjusting the ends of said lubricanttransporting bar.

' 3. In a car axle lubricator, an axle provided at its end with spacedbearing members, a lubricant transportingba'r provided with hearingopenings loosely receiving and taking over said spaced bearing members,a bow spring provided with openings loosely receiving and taking oversaid spaced bearing members and having its free ends bearing against theends of said transporting bar, and spring retaining members adjustablymounted on said bearing members whereby said transporting bar is'adaptedto ride and travel upon said bearing members and the ends independentlyadjusted through said adjustably mounted spring retaining members. I

at. In combination with an aXle,'a journal box including an extendedfront provided with an annular shoulder having lubricant receiving anddischarging ports above and below said axle; a transverse bar extendingacross the front of said axle and'rotatable iusaid extendedcfront, saidbar being provided at its ends with oppositely arranged lubricantreceiving cups traversing said annular shoulder and receiving anddischarging lubricant from and through said ports be low and ab ve saidaxle, respectively, a bow spring for retaining said bar in place, andspaced bar and spring carrying and adjusting members on said axle uponwhich the intermediate portions of said transverse bar and bow springare mounted and adjusted.

In testimony whereof, I hereunto set my hand this 8th may of Aug. 1914.
